Has anyone tried to instal Dr.HD F15 software on TM5402?
In case of F16 and its brothers Clarketech 5000combo+ and TM6900super it was possible in this way:
1) Open firmware for f16 in hex editor
2) Offset 0000000010-00 you will have for firmware technomate 08, for f16 22, for CT 10
3) change it for 08
4) now your TM6900 will think that it is firmware for TM, and lets you instal it
08 - Technomate id
22 - Dr hd F16 id
10 - Clarktech id

I would be great to have dr.hd f15 software with spectrum analiyzer and hd GUI.

You obviously do for your own resposibility.
